The correct option is this: PROTO ONCOGENES BECOMES ONCOGENES.
Proto oncogenes genes are those genes that regulate the process of normal cell division in the living system. These cells starts cell division when necessary and terminate the cell division when the necessary cells have been formed. When these genes lose the power to regulate cell division, the cells continue to divide indefinitely without stopping and this leads to a medical condition called cancer. At this stage, the proto oncogenes have been turned into oncogenes, which are genes that caused uncontrolled cell cycle divisions.
DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Explanation:
body temperature and hormone levels. give two examples from the reading of how living things respond to changes in their environment. sweating on a hot day and squinting at the sunlight. ... reproduction, based on genetic code (DNA), grow and develop, obtain and use materials and energy, respond to environment, organized.
Answer:
from the image:
1. eight
2. four
3. less than
Explanation:
from the data given...
n= 4
where n= # of genes
&, the extreme # of segments= 
Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.
...one gene may have 2 alleles
An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...
∴4 genes= 4 × 2=<u> </u><u>8 segments</u>
<u />
<u>Thus, each allele gives </u> 
= <u>1 segment</u>
<u></u>
<u></u>
